WARNING

For indoor installations, as an additional measure of safety, National Combustion Co. strongly recommends installation of suitable Carbon Monoxide detectors in the vicinity of this appliance and in any adjacent occupied spaces.

AVERTISSEMENT

Pour des installations intérieures, National Combustion Co. recommande fortement, comme mesure de sécurité supplémentaire, l’installation de détecteurs de monoxyde de carbone adaptés dans le voisinage de l’appareil et dans chacune des pièces habitées adjacentes.

2.A Combustion Air

Brute Deluxe boilers and water heaters must have provisions for combustion and ventilation air in accordance with the applicable sections addressing requirements for air for combustion and ventilation of

the National Fuel Gas Code, ANSI Z223.1. In Canada, the applicable sections of the Natural Gas and Propane Installation Code (CSA B149.1) must be followed. In

all cases any and all applicable local installation codes

must also be followed.

A Brute Deluxe appliance may receive combustion air from the space in which it is installed,

or it can be ducted directly to the unit from the outside. Proper ventilation air must be provided in either case.

2.A.1 Combustion Air From Room

In the United States, the most common requirements specify that the space shall communicate with the outdoors in accordance with method 1 or 2,

which follow. Where ducts are used, they shall be of

the same cross-sectional area as the free area of the

openings to which they connect.

Method 1: Two permanent openings, one

commencing within 12 inches (30 cm) of the top and one commencing within 12 inches (30 cm) of the bottom, of the enclosure shall be provided. The

openings shall communicate directly, or by ducts, with the outdoors or spaces that freely communicate

with the outdoors. When directly communicating

with the outdoors, or when communicating to the outdoors through vertical ducts, each opening shall have a minimum free area of 1 square inch per 4000

Btu/hr (5.5 square cm/kW) of total input rating of all equipment in the enclosure. When communicating to the

outdoors through horizontal ducts, each opening shall have a minimum free area of not less than 1 square inch per 2000 Btu/hr (11 square cm/kW) of total input rating

of all equipment in the enclosure. Table 1 shows data for this sizing method, for each Brute Deluxe model.

Method 2: One permanent opening, commencing

within 12 inches (30 cm) of the top of the enclosure, shall be permitted. The opening shall directly

communicate with the outdoors or shall communicate through a vertical or horizontal duct to the outdoors or spaces that directly communicate with the outdoors and shall have a minimum free area of 1 square inch

per 3000 Btu/hr (7 square cm/kW) of the total input rating of all equipment located in the enclosure. This

opening must not be less than the sum of the areas of

all vent connectors in the conned space.

Other methods of introducing combustion and ventilation air are acceptable, providing they conform to the requirements in the applicable codes listed

above.

In Canada, consult local building and safety codes or, in absence of such requirements, follow CSA

B149.1, the Natural Gas and Propane Installation Code.

The combustion air can be taken through the

wall, or through the roof. When taken from the wall,

it must be taken from out-of-doors by means of the Bradford White horizontal wall terminal (see Table 1).

When taken from the roof, a eld-supplied rain cap or

an elbow arrangement must be used to prevent entry of rain water (see Figure 3).

Use single-wall galvanized pipe for the

combustion air intake (see Table 1 for appropriate

size). Route the intake to the heater as directly as possible. Seal all joints with tape. Provide adequate hangers. The unit must not support the weight of the combustion air intake pipe. Maximum linear pipe length allowed is 50 feet (15.2m). Three elbows have been calculated into the 50-foot (15.2m) linear run. Subtract 10 allowable linear feet (3.0m) for every

additional elbow used (see Table 1). When fewer than

3 elbows are used, the maximum linear pipe length allowed is still 50 feet (15.2m).

Material.

The connection for the intake air pipe is on the

lter box. The Brute Deluxe appliances may have

venting and combustion air ducting attached to the top

or the back. They are shipped with the connections at the top. For attaching either or both pipes to the back, the mounting anges are reversible by removing the mounting screws and orienting the anges in the desired position. Replace the screws after positioning anges. Run a bead of silicone around the collar and slide the pipe over the collar. Secure with sheet metal screws.

In addition to air needed for combustion, air shall also be supplied for ventilation, including all air required for comfort and proper working conditions

for personnel. The Brute Deluxe loses less than 1

percent of its input rating to the room, but other heat

sources may be present.

Category I vent system, and includes rules and tables

to size these vent systems. If the Brute Deluxe’s

vertical vent system does not satisfy the criteria for Category I venting, it must be vented as a Category III

system.

All Brute Deluxe vent systems which discharge

horizontally (without the use of a power venter) are

considered Category III vent systems.

2.B.2 Category I Vent

When vented as a Category I appliance, the

vent system must conform to the National Fuel Gas Code (ANSI Z223.1-Latest Edition) in the U.S., or in Canada, to the Natural Gas and Propane Installation Code (CSA B149.1 latest edition). The vent system must be sized and installed for a Category I FanAssisted Appliance.

If chimney height is greater than 25 feet, or

if multiple units are vented into the same vertical vent, a barometric damper must be installed on each

appliance, such that the ue draft does not exceed (negative) 0.1 in. w.c.

If using a power venter for any type of Category

I venting, the draft should be set between (negative)

0.01 and 0.05 in. w.c.

2.B.3 Common Venting Systems

Brute Deluxe units are Category I fan-assisted

when vented vertically and adhering to all applicable

codes. Brute Deluxe units are not allowed to be

vented into a common horizontal vent system, unless a properly sized vent fan is used, and the common vent system is properly designed by the vent fan

manufacturer or a qualied engineer. When common

venting Brute Deluxe fan-assisted unit with other appliances through one shared vertical duct called a

“common vent”, special care must be taken by the installer to ensure safe operation. In the event that

the common vent is blocked, it is possible, especially for fan-assisted devices, to vent backwards through non-operating appliances sharing the vent, allowing

combustion products to inltrate occupied spaces.

If the appliances are allowed to operate in this condition, serious injury or death may occur.

2.B Venting

2.B.1 Vent Categories

Depending upon desired Brute Deluxe venting, it may be considered a Category I or a Category III

appliance. In general, a vertical vent system will be a Category I system. However, in rare instances, a

Brute Deluxe’s vertical vent system may be considered

Category III. In the U.S., the National Fuel Gas Code (ANSI Z223.1), or in Canada the Natural Gas and Propane Installation Code (CSA B149.1), denes a

WARNING

Operation of appliances with a blocked common vent may lead to serious injury or death. Safety devices must be implemented to prevent blocked common vent operation. If safe operation of all appliances connected to a common vent cannot be assured, including prevention of spillage of flue gasses into living spaces, common venting should not be applied, and appliances should each be vented separately.

AVERTISSEMENT

Le fonctionnement d’appareils connectés à un évent commun bouché peut provoquer de sérieuses blessures corporelles ou la mort. Des dispositifs de sécurité doivent être mis en place pour empêcher que les appareils soient utilisés avec un évent commun bouché. Si un fonctionnement sécuritaire de tous les appareils reliés à un évent commun et si la prévention des dégagements accidentels de gaz de combustion dans des zones habitées ne peuvent pas être assurés, un évent commun ne doit pas être mis en place et les appareils doivent être munis d’évents individuels séparés.

It is for this reason that, in addition to

following proper vent sizing, construction and safety

requirements from the National Fuel Gas Code, ANSI Z223.1 or in Canada, from the Natural Gas and Propane Installation Code (CSA B149.1) as

well as all applicable local codes, it is required that installers provide some means to prevent operation

with a blocked common vent. It is suggested that a

blocked vent safety system be employed such that if the switch from one appliance trips due to excessive stack spill or back pressure indicating a blocked vent condition, that all appliances attached to the vent be

locked out and prevented from operating. Note that

the Brute Deluxe is equipped with a blocked vent

safety (pressure) switch, as shipped. However, this

safety switch has only been designed and tested to

be eective in installations where the Brute Deluxe is vented separately and NOT common vented with other appliances. As an additional precaution, it is

recommended that a Carbon Monoxide (CO) alarm be installed in all enclosed spaces containing combustion

appliances. If assistance is required in determining

how a blocked vent safety system should be connected to a Bradford White product, please call Applications

Engineering at the Rochester phone number on the back cover of this manual.

Refer to the installation and operating

instructions on all appliances to be common vented for instructions, warnings, restrictions and safety

requirements. If safe operation of all appliances

connected to a common vent cannot be assured,

including prevention of spillage of ue gases into

living spaces, common venting should not be applied,

and appliances should each be vented separately.

2.B.4 Category III Vent

When the Brute Deluxe is vented with horizontal discharge, it must be installed per this installation manual and the venting system manufacturer’s

installation instructions. The vent system must be

sealed stainless steel, per Table 4.

2.C Locating Vent & Combustion Air Terminals

2.C.1 Side Wall Vent Terminal

The appropriate Bradford White side wall vent terminal must be used, and is listed in the installation

and operation manual. The terminal provides a means

of installing the vent piping through the building wall,

and must be located in accordance with ANSI Z223.1/ NFPA 54 and applicable local codes. In Canada, the installation must be in accordance with CSA B149.1 and local applicable codes. Consider the following

when installing the terminal:

1. Figure 4 shows the requirements for mechanical vent terminal clearances for the U.S. and Canada.

2. Locate the vent terminal so that vent gases cannot be drawn into air conditioning system inlets.

3. Locate the vent terminal so that vent gases cannot

enter the building through doors, windows, gravity

inlets or other openings. Whenever possible,

locations under windows or near doors should be

avoided.

4. Locate the vent terminal so that it cannot be blocked by snow. The installer may determine that

a vent terminal must be higher than the minimum

shown in codes, depending upon local conditions.

5. Locate the terminal so the vent exhaust does not settle on building surfaces or other nearby objects. Vent products may damage such surfaces or objects.

2.C.2 Side Wall Combustion Air Terminal

The Bradford White side wall combustion air terminal

(listed in Table 1) must be used when the unit takes its combustion air through a duct from a side

wall. Consider the following when installing the

terminal:

1. Do not locate the air inlet terminal near a source of corrosive chemical fumes (e.g., cleaning uid, chlorinated compounds, etc.)

2. Locate the terminal so that it will not be subject to damage by accident or vandalism.

3. Locate the combustion air terminal so that it cannot be blocked by snow. The National Fuel Gas Code requires that it be at least 12 inches (30 cm)

above grade, but the installer may determine it

should be higher, depending upon local conditions.

4. If the Brute Deluxe is side-wall vented to the same wall, locate the vent terminal at least 3 feet (0.9m)

horizontally from the combustion air terminal,

and locate the vent terminal at least 1 foot (0.3m)

above the combustion air terminal (see Figure 4).

2.C.3 Vertical Vent Terminal

When the unit is vented through the roof, the

vent must extend at least 3 feet (0.9m) above the point at which it penetrates the roof. It must extend at least 2 feet (0.6m) higher than any portion of a building within a horizontal distance of 10 feet (3.0m), and high

enough above the roof line to prevent blockage from

snow. When the combustion air is taken from the roof, the combustion air must terminate at least 12" (30cm)

below the vent terminal (see Figure 3).

2.C.4 Vertical Combustion Air Terminal

When combustion air is taken from the roof, a

eld-supplied rain cap or an elbow arrangement must

be used to prevent entry of rain water (see Figure 3). The opening on the end of the terminal must be at least

12" (30cm) above the point at which it penetrates the

roof, and high enough above the roof line to prevent

blockage from snow. When the vent terminates on the

roof, the combustion air must terminate at least 12"

(30cm) below the vent terminal.

2.D Common Vent Test — Boilers

When an existing boiler is removed from a common venting system, the common venting system is likely to be too large for proper venting of the

appliances remaining connected to it.

At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system

are not in operation.

1. Seal any unused openings in the common venting

system.

2. Visually inspect the venting system for proper

size and horizontal pitch and determine there is

non blockage or restriction, leakage, corrosion

and other deciencies which could cause an

unsafe condition.

3. Insofar as it is practical, close all building doors

and windows and all doors between the space in

which the appliances remaining connected to the

common venting system are located and other

spaces of the building. Turn on clothes dryers

and any appliance not connected to the common

venting system. Turn on any exhaust fans, such

as range hoods and bathroom exhausts, so they

will operate at maximum speed. Do not operate a

summer exhaust fan. Close replace dampers.

4. Place in operation the appliance being

inspected. Follow the lighting instructions.

Adjust thermostat so appliance will operate

continuously.

5. Test for spillage at the draft hood relief opening

after 5 minutes of main burner operation. Use

the ame of a match or candle, or smoke from a

cigarette, cigar or pipe.

6. After it has been determined that each appliance

remaining connected to the common venting

Page 14

Bradford White Corp

system properly vents when tested as outlined above, return doors, windows, exhaust fans,

replace dampers and any other gas burning appliance to their previous conditions of use.

7. Any improper operation of the common venting

system should be corrected so that the installation

conforms with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CSA B149.1, Natural Gas and Propane Installation Codes.

When resizing any portion of the common venting system, the common venting system should be resized to approach the minimum size as determined using the appropriate tables in

Appendix F in the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CSA B149.1, Natural Gas and Propane Installation Codes.

2.D Véricationdeséventscommuns— Chaudières

Lorsqu’une chaudière existante est déconnectée

du réseau d’évents commun, ce réseau d’évents commun devient probablement trop grand pour les appareils qui lui restent connectés. Lorsqu’une chaudière existante est retirée, les étapes suivantes doivent être accomplies pour chaque appareil qui reste connecté au réseau d’évents commun utilisé, alors que les autres appareils qui sont encore connectés au réseau commun d’évents ne sont pas en fonctionnement.:

1. Sceller toutes les ouvertures non utilisées du système d'évacuation.

2. Inspecter de façon visuelle le système d'évacuation pour déterminer la grosseur et l'inclinaison horizontale qui conviennent et s'assurer que le système est exempt d'obstruction, d'étranglement, de fuite, de corrosion et autres défaillances qui pourraient présenter des risques.

3. Dans la mesure du possible, fermer toutes les portes et les fenêtres du bâtiment et toutes les portes entre l'espace où les appareils toujours raccordés au système d'évacuation sont installés et les autres espaces du bâtiment. Mettre en marche les sécheuses, tous les appareils non raccordés au système d'évacuation common et tous les ventilateurs d'extraction comme les hottes de cuisinière et les ventilateurs des salles de bain. S'assurer que ces ventilateurs fonctionnent à la vitesse maximale. Ne pas faire fonctionner les ventilateurs d'été. Fermer les registres des cheminées.

4. Mettre l'appareil inspecté en marche. Suivre les instructions d'allumage. Réegler le thermostat de façon continue.

5. Faire fonctionner le brûleur principal pendant 5 min ensuite, déterminer si le coupe-tirage déborde à l'ouverture de décharge. Utiliser la

amme d'une allumette ou d'une chandelle ou la

fumée d'une cigarette, d'un cigare ou d'une pipe.

6. Une fois qu'il a été déterminé, selon la méthode indiquée ci-dessus, que chaque appareil raccordé au système d'évacuation est mis à l'air libre de façon adéquate. Remettre les portes et les fenêtres, les ventilateurs, les registres de cheminées et les appareils au gaz à leur position originale.

7. Tout mauvais fonctionnement du système d'évacuation commun devrait être corrigé de façon que l'installation soit conforme au National Fuel Gas Code, ANSI Z223.1/NFPA 54 et (ou) aux codes d'installation CSA-B149.1. Si la grosseur d'une section du système devrait

être modié, le système devrait être modié pour

respecter les valeurs minimales des tableaux pertinents de l'appendice F du National Fuel Gas Code, ANSI Z223.1/NFPA 54 et (ou) les codes d'installation CSA-B149.1

2.E Vent Terminals for Outdoor Units

For outdoor applications, the vent and

combustion air openings must be covered with proper terminals to prevent rain, snow and other objects from

falling into the Brute Deluxe.

Outdoor Vent / Air kit part numbers are shown in

Table 6. These kits contain parts for both combustion

air inlet and exhaust vent connections. An angled sheet

metal assembly with louvers replaces the sheet metal

assembly with the air collar. An adapter, a 12" length

of pipe, and a rain cap are included for the exhaust

vent opening.

If local codes allow, Bradford White kits are

not required for outdoor units. The installer may use

12" of appropriately sized galvanized single wall or

b-type vent pipe and a rain cap for the exhaust vent. In

addition, an appropriately sized galvanized 90° elbow, positioned with the opening facing down, may be used

on the combustion air inlet.
